Apologises if there has been a Post in the past concerning this subject. I couldn't find it if there was.

I have managed to pick up a Mackie C4 (not the latest USB version) midi controller cheap. I am running Cubase 7 and Ableton 8 on the PC. I am aware the controller is not supported by these DAWs - unfortunately!

I am not particularly bothered about it not being able to control the DAWs themselves, but is there a way of creating your own patches/programs to control a VSTi? As you may well know the majority of VSTi parameters are controlled by Midi CC# rather than Sysex or RPN. There is not a 'Learn' feature on the controller, but there is on the parameters of a VSTi.

Has anyone found a way of converting Midi CC# data of a VSTi to RPN or Sysex data on to the Mackie C4 control knobs via the Mackie C4 Commander software so the VSTi can be controlled in realtime?

The Mackie Controllers are"dumb", in that they basically don't have anything to do with software, they just send out the data they are programmed to do, and rely on the host software to manage this. If none of your hosts support these, they will be less useful.

You can always use a MIDI monitor program to examine the MIDI data sent by the controllers and learn stuff manually, but it's a tedious and poor way to use them, particularly when they were designed from a non-mapping intelligent use to begin with. But I'd probably start there first...
